Comparison of the Efficacy of Natural Adsorbents From Jackfruit and Coconut Shell Waste for the Adsorption of Impurities of Dye and Wastewater

Abstract

In the present work, jackfruit and coconut shell waste from natural resources are used to synthesize adsorbents by the carbonization method for the removal of methylene blue dye and impurities from wastewater. Adsorbents from jackfruit and coconut shell wastes were synthesized at 550°C for 4 h in the carbonization method and activated by acid treatment. Adsorbents synthesized from jackfruit and coconut shell waste were characterized using techniques such as the Brunauer-Emmett-Teller method, scanning electron microscopy, and X-ray diffraction to study and compare their properties. This research concludes that jackfruit waste adsorbents act better than coconut shells and are similar to conventional ones. At adsorption parameters of 30°C, pH = 7, 3 g adsorbent quantity, reusable three times, and a 24 h contact period, the adsorption of dye and debris from wastewater jackfruit waste is a preferable choice. Also, the qualities of traditional activated charcoal are contrasted with those of jackfruit and coconut shell adsorbents. Purification of wastewater with jackfruit adsorbent was > 96.3% as compared to coconut shell adsorbent, which had a 69.3% waste removal efficiency. The results demonstrated that jackfruit waste, due to its better structure, morphology, and surface area, would be the most effective adsorbent for removing methylene blue dye and contaminants from wastewater.
